Firm Grip LacesThick Flat 3/4" Wide Shoelaces Solid Color Strings for All Shoe Types - Sneaker Shoe Laces

I don't know what those measurements mean because i'm only 12.i have superstars in 6 1/2 in youths(not kids,youths!!!) are those laces suitable mine?

I have addidas superstats in a Men's Size 12. Are these long enough?

Good for superstar?

What size shoe will this fit? Are they too long for a size 9.5?
